The U.S. Department of Energy said Sunday that it is set to announce a “major scientific breakthrough” in the field of nuclear fusion.

The British newspaper Financial Times >(FT) reported hours earlier that scientists at the Lawrence Livermore National Laboratory (LLNL), located in California, recently obtained a net energy gain from an experimental fusion reactor.

< p class="e-p">It would mark the first time that researchers have managed to produce more energy in a fusion reaction – like the one that powers the Sun – than they have consumed in the course of time. process, which would be a significant step forward in the search for carbon-free energy.

This is the US Secretary of Energy, Jennifer Granholm, who will announce this significant breakthrough, likely on Tuesday.

The fusion reaction that produced a 120% net energy gain occurred at past two weeks, the FT reported, citing three people who had knowledge of the preliminary results.

Nuclear fusion is considered by its defenders as the energy of tomorrow, in particular because it produces little waste and no greenhouse gases.

Si this breakthrough…is real, it could be a game-changer for the planet, California Congressman Ted Lieu tweeted after the FT report was released.

Fusion differs from fission, a technique currently used in nuclear power plants, which consists of breaking the bonds of heavy atomic nuclei to recover energy from them.

Fusion is the reverse process: you marry two light atomic nuclei to create a heavy one. In this case two isotopes (atomic variants) of hydrogen, giving rise to helium.

The LLNL installation consists of nearly 200 lasers the size of three football fields, which target a tiny point with high levels of energy to trigger a fusion reaction.
